thirty years ago my old man bought a 73 jimmy and has put it over 400k. I was brought home from the hospital when I was born. When I was fifteen I rolled it for him on a country road, we rebuilt. Two years ago he picked himself up a 91 k5 so as he went into retirment he would have a newer rig. And as of today I just picked it up from him for 1500 bucks. Needs some work, now I will get my chance to make it fresh again and build it just like I dreamed when I was a kid. Pretty sure you chaps will be a great help. If there is anything that is a notorious problem with these rigs please let me know. Like I said it's a 73 jimmy with a 350, th350 auto, np203 transfer, I am unsure of what axles are underneath her but know that it's running 373's, you just have to love your heritage.
